摘要：

Interpolymer complexation between poly(N-isopropylacrylamide) (PNIPAAM) and the hydroxyl-containing polymers poly (p-vinylphenol) (PVPh) and poly(2-hydroxypropyl methacrylate) (PHPMA) has been studied. A common solvent for PNIPAAM and PHPMA has been selected from phase behavior studies of these polymers in aqueous-methanolic solutions. Precipitates of PNIPAAM/PVPh in methanol at room temperature and PNIPAAM/PHPMA in a mixture methanol/water (56/44) at -11degreesC have been isolated. The compositions of the resulting complexes have been determined. Calorimetric measurements indicate that all PNIPAAM/PVPh complexes present a similar T-g which does not depend on feed composition, and is higher than that of the component polymers, whereas PNIPAAM/PHPMA complexes present an intermediate composition-dependent T-g. Thermal stability of all complexes has also been studied.
